Xu Mumu transmigrated into a book and became the female lead's cousin. Her family were considered the worst sort of people by everyone else, but Xu Mumu thought they were adorable: her troublemaking mother, drama-loving father, lazy older brother, and mischievous younger brother made for a lively household.
So when her cousin found money, Xu Mumu won a scholarship. When her cousin's family started a business, her older brother went to the city to work as a laborer. And by the time her cousin's family had grown rich, Xu Mumu had already brought her own family to the city.
